Welcome back to TechCrunch Mobility, your hub for the future of transportation and now, more than ever, how AI is playing a part.

On the latest episode of Equity, we debate whether Apple's lawsuit will cast over OpenAi's much-discussed plans to get into hardware and go public.

I had 800-something LeetCode problems solved when I interviewed at Amazon. I figured I was ready. Two-pointer, sliding window, DP, graphs — I'd drilled all of it. I could smell a "this is a heap problem" from the second line of a prompt. Then they handed me a repository. Not a blank editor — an actual codebase that was partly built, and the task was to implement a couple of new features and debug the existing ones that were broken. Real code I hadn't written, a test suite I had to get green, ...

Building Production-Grade LLM Evaluation Pipelines: From Vibes to Metrics How we replaced "looks good to me" with automated evaluation catching 92% of hallucinations before deployment The Problem: Why "Vibe Checks" Fail in Production Three months ago, our team shipped a RAG-based customer support assistant. It worked great in testing — we'd ask it questions, read the answers, and say "yeah, that looks right." Then it hit production. A customer asked about their bil...

Optimizing RAG at Scale: Chunking, Retrieval, and the Bayesian Search That Cut Latency 40% How we moved from "semantic search + hope" to a measured, tunable retrieval pipeline with 95% recall@10 The RAG Reality Check Everyone ships RAG the same way: chunk by 512 tokens, embed with text-embedding-3-small , top-k=5, stuff into context. It works for demos. Then you hit production: Legal contracts: 512 tokens splits clauses mid-sentence API docs: 1000-token chunks...

A notification badge looks like a small feature. In a distributed application, it can expose a large architectural assumption. I recently investigated a badge that sometimes stayed stale in an ASP.NET Core and Blazor application running across multiple server instances. The notification itself had been created successfully. Durable state was correct. A separate push path could also complete. Yet the visible count did not always change until the user left the screen and returned. The bug wa...

Sentence boundary detection sounds boring. Split on . ? ! , done, right? Anyone who has tried knows otherwise. Abbreviations, decimals, URLs, nested quotes, ellipsis, legal citations, biomedical jargon—each one turns "split text" into a language-specific puzzle. Two Python libraries tackle this problem with different philosophies. pysbd has been the go-to since 2020 with 22 languages, ported from Ruby's pragmatic segmenter [1]. yasbd-lib is newer, covers 39 languages, and takes a dif...

Un deploy de frontend falló. No había cambiado código en el pipeline, nose había subido ninguna dependencia, el lockfile era byte por byte idéntico al del deploy que había pasado en verde 23 horas antes. El falló: ERR_PNPM_AUDIT_BAD_RESPONSE The audit endpoint (at https://registry.npmjs.org/-/npm/v1/security/audits/quick) responded with 410: {"error":"This endpoint is being retired. Use the bulk advisory endpoint instead."} npm había retirado el endpoint al que pnpm audit h...

🚀 The AI Wave of 2026: 10 New Things Every Developer Should Know AI is evolving faster than ever. If you blink for a month, you'll probably miss a breakthrough. 2026 isn't just about "using ChatGPT." It's about AI agents collaborating with each other, coding entire applications, browsing the web, generating videos, remembering conversations, and even running businesses. As developers, staying updated isn't optional anymore. Here are 10 of the biggest AI trends shaping 202...

The bug report came in on a Tuesday. One line: "Your app says I hit 400 kmph. I was at a red light." He wasn't lying. Neither was the app. The phone genuinely believed it, and that is the interesting part. I work on mileage tracking. If you have ever had an app quietly log your drives for expenses or taxes, that is the category. Trip accuracy is not a feature of the product. It is the product. When we started, ours sat around 50 percent, and almost every missing point traced back to...

I've migrated a few real environments from Terraform to OpenTofu now, and the good news is that a careful migration is almost boring. The state format is compatible, the CLI is a near drop-in, and the whole thing can be done with a rollback path at every step. The bad news is that "almost boring" still has a couple of sharp edges, and the teams that get hurt are the ones who skip the parity check and go straight to apply . Here's the calm, low-risk playbook I actually follow. Step 0...

What Is a Focus Session? A focus session is a bounded block of time — typically 20 to 50 minutes — dedicated to a single, clearly defined task with all distractions removed. Unlike a general 'work block', a focus session has three hard requirements: a specific intention set before the timer starts, uninterrupted execution during the block, and a brief review at the end. This structure is what separates a focus session from just sitting at your desk hoping something happens. The mechanism ...

Hi everyone! 👋 I'm Alex, and like many of you, I've spent countless hours in "setup hell." Every time I started a new Python project, I found myself doing the exact same boring things: configuring SQLite connections, setting up logging, wrestling with directory structures, and manually wiring up authentication. I realized I was building the same "skeleton" over and over again instead of focusing on the actual business logic. So, I decided to switch the script. I’ve spent the las...

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system tha...

Clap on. Clap off. Well, more like, Clap, pause for half a beat but no longer because otherwise it'll stop hearing you, clap again because you waited too long, clap louder and faster, that didn't work, clap two more times, and suddenly: on. The Clapper didn't always work - and even when it did, it […]
